Fixed Frequency Synthesiser For Radar Systems

Z-Communications announced a new S-band Fixed Frequency Synthesizer which is an excellent choice for radar applications which require operation over the industrial temperature range of -40 to 85°C.

The SFS6265A-LF is a low cost phase locked loop that operates at 6265 MHz with an external 100 MHz reference oscillator and features a typical phase noise of -89 and -90dBc/Hz at the 1kHz and 10kHz offsets, respectively.

The new RoHS compliant synthesiser is designed to deliver a typical output power of +3dBm while operating off a VCO voltage supply of 5Vdc and drawing 35mA (typical) and a phase locked loop voltage of 3Vdc while drawing 11mA (typical).

Additional features include a typical 2nd harmonic suppression of -20dBc and spurious suppression of -65dBc. It is housed in Z-COMM’s standard PLL-V12N package measuring 0.6 in. x 0.6 in. x 0.13 in. The SFS6265A-LF is also ideal for automated surface mount assembly and is available in tape and reel packaging.
